Wuhan Textile University: A New Way Of "Modern Textile" Scientific Research

Recently, the top ten news of China's textile industry in 2020 was announced. Wuhan University of textile won the second prize of the national science and technology progress award by successfully displaying the "fabric version" of chang'e-5 lunar flag on the moon and developing high-performance industrial silk high-quality energy-saving twisting equipment.

"It is the University's responsibility and responsibility to give full play to the advantages of characteristic disciplines, to break through the key technologies of" neck sticking "and to actively integrate into the national strategic needs," said Professor Xu Weilin, President of Wuhan Textile University.

"Bright sword", bring "China Red" into space

"If the miracle has color, it must be China red!" the beautiful collision between textile and chemical engineering disciplines, and the eight year hard work of teachers of related disciplines, have made the first "fabric version" of the moon's five-star red flag come out gorgeous. Since accepting this important space scientific research task, Professor Xu Weilin, the project leader, has set up a research team composed of researchers from textile and chemical fields according to the interdisciplinary points contained in the project.

In the early stage of development, the team started from the molecular structure characteristics, physical and chemical characteristics of hundreds of fibers, combined with the comprehensive analysis of various factors such as textile processing performance and fabric high-quality requirements, and delineated domestic high-performance aramid fiber as textile raw material. However, the aramid fiber has a large initial modulus, so it is difficult to process high-quality yarn. After many attempts of re research and re experiment, the team applied the "high efficiency and short process embedded composite spinning technology", which was awarded the first prize of national science and technology progress, during which the yarn production was put into practice, and the "fabric version" national flag also had the basic rudiment.

However, when the flag, which has overcome the technical difficulties of high-performance aramid fiber dyeing, went to Beijing for space environment simulation experiment after a series of bottom-up experiments, there was a problem of pigment cross-linking, and the development was once in a bottleneck.

      "Since the pigments on the market can't fully meet the experimental conditions, we'll develop them ourselves!" after the conversion of ideas, the team finally used the previous original achievements - "superfine pulverization of high-quality natural polymer materials and high value-added reuse technology" to prepare micro nano silk powder, and developed a new color paste, which "put on a protective clothing" for the color of the national flag The problem of color matching under extreme conditions has been solved qualitatively, and the core technical difficulty of this national flag has finally been achieved.

While undertaking the project of displaying the national flag on the lunar surface, the relevant team of the university has also undertaken the aerospace projects such as the elastic thermal insulation components of the "tianwen-1" Mars probe, as well as relevant military scientific research projects.

"Modern textile" is far from spinning and weaving in the traditional sense, but an important field of great achievements. By gathering the strength of the whole school, starting from the basic scientific problems of fiber materials and textile science and technology, and improving the technical ability and advantages of "modern textile", the school has broken through a number of "neck sticking" key technologies in the field of processing new fiber materials and products in the national major strategic project, which has become the scientific and technological confidence and cultural confidence rooted in the hearts of teachers and students of the school. " Wuhan Textile University Party Secretary Tian Huiyu said.

"Tackling difficulties" and implementing scientific research projects in the industrial chain

After years of continuous cultivation and construction, the Ministry of science and technology has officially approved the construction and operation of the State Key Laboratory of new textile materials and advanced processing technology jointly constructed by the Ministry of science and technology of Wuhan Textile University. On the basis of traditional textile disciplines, the platform highlights the characteristics of textile materials and their processing technology through the intersection with materials, chemical engineering, electromechanical, computer, mathematics, physics, biology and other disciplines. It condenses three key research directions: fiber structure and performance, new theory and method of textile processing, new equipment and information technology of textile processing. The platform is positioned to serve the development and progress of local economy and textile industry in Hubei Province, and form an effective complementary with other national scientific research platforms in the same industry in the research direction, and lay a solid foundation for the development of Frontier basic research and applied basic research in the future.

      In view of the bottleneck problem of high-performance industrial yarn twisting yarn quality is difficult to guarantee and the technical equipment has been monopolized by foreign countries for a long time, Professor Mei SHUNQI, deputy director of the laboratory, through theoretical innovation of equipment design and manufacturing, has broken through the technical problems of high-performance industrial yarn difficult to achieve high-quality twisting and winding, high energy consumption of equipment and low efficiency, and established the quality and energy consumption control of twisting yarn Methods: the "one-step" high-efficiency energy-saving direct twisting technology of high-strength synthetic fiber industrial yarn was invented, the constant tension anti-static twisting technology of ultra-fine glass fiber industrial yarn was invented, and a series of high-quality energy-saving twisting equipment for high-performance industrial yarn were developed. The overall technology of the project has reached the international advanced level, and the equipment application accounts for more than 50% of the domestic and foreign market segments, which has promoted the transformation and upgrading of the industry and achieved remarkable economic and social benefits. The project cooperative enterprise has also become the internationally famous major R & D and manufacturing base of high-grade industrial line twisting equipment. In 2020, the achievement won the second prize of national science and technology progress award.

  "Facing the application, mining common problems, deeply carrying out scientific research, forcing technological innovation through actual projects, and implementing scientific research projects in the industrial chain are not only the survival way of our industry colleges and universities with distinctive characteristics and multi-disciplinary coordinated development, but also the only way to build a first-class teaching and Research University rooted in the industry, serving the local and domestic" Professor Xu Weilin, President of the Textile University and director of the State Key Laboratory of textile new materials and advanced processing technology jointly constructed by the Ministry and the province, spoke with emotion.

"Seeking innovation" and striving to be a valuable researcher

In 2020, Professor Wang Hua, a leader in the field of high-performance fibers and nonwovens, and winner of the second prize of national science and technology progress award, joined Wuhan Textile University. From being employed as a "sunshine scholar" to joining full-time, Wang Hua has a friendship with Textile University for more than ten years.

"Our team has obvious advantages in basic theory, and Professor Wang Hua's team has engineering advantages. Although they are in different cities, we share the same interests and complement each other. The two teams have formed a team to carry out scientific research. It's very happy to cooperate!" said Wang Luoxin, President of the school of materials of Textile University, who has worked closely with Wang Hua for many years. After 8 years of long-distance running, the team has overcome many obstacles from the selection of raw materials to the industrialization of filter bags. In 2018, the project was officially put into operation, bringing a new change in the fields of environmental protection and new energy. The patent was transferred to Yingcheng Tianrun industrial cloth Co., Ltd. with a valuation of 10 million yuan and put into production. "I like the atmosphere of Textile University. I attach great importance to talents. I have a rigorous style of work. I have a strong atmosphere for doing well here. Naturally, I am willing to do more and do great things," said Wang Hua, who has been in Hubei Province for a few months.

In recent years, a large number of high-end leading talents have successively invented the inorganic modification technology of fiber surface, carrier dyeing technology, three-dimensional weaving technology and equipment, which has broken through the bottleneck of high-performance fiber difficult to color and process into high-quality products; The embedded composite spinning technology has broken the international record of ultra-high count yarn of civil textiles and woven the lightest fabric in the world A series of remarkable achievements have been made.

Last summer, Wuhan Textile University launched more than 470 transformable achievements in the special cloud promotion activity of "connecting 100 schools to 1000 fruits" in Wuhan, Hubei Province, which was revived after the epidemic.
